People are voting emotionally.

A bit overrated, but still an amazing film

It's a mild crowd pleaser for people who are exhausted by blockbusters.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
